SPECIFICATION forming part of Letters Patent NO. 424,051, dated March25, 1890.

Application ledJuly 5, 1889.

To all whom it may concern.-

Beit known that I, MARTIN A. DILLEY, a citizen of the United States ofAmerica, residing at Wasepi, in the county of St. Joseph and State ofMichigan, have invented certain new and useful Improvements inRailroadtignals, of which the following is a specifica- 1on. I v

My invention has relation to railroad-signals of that class used toindicate danger or safety to approaching trains; and the object is toprovide a signaling device carrying an indicating-lantern which can bereadily removed and replaced without the usual climbing to it by ladderor other means of reaching a signal placed at an altitude.

I accomplish the purpose of my invention by means of the Inechanism andappliances illustrated in the accompanying drawings, wherein- Figure 1is a front View in elevation. Fig. 2 is a side View of .the same. Fig. 3is aview of the lantern-frame on a larger scale than shown in thepreceding figures. Fig. 4 is a view of the lantern, showing the journalsof different diameters. Fig. 5 is a side view of the lantern arranged inthe frame, on larger scale, the apron being shown in dotted lines aslifted by the force of the wind. Fig. 6 is a view showing thesignal-stad tilted and the lantern in position to be removed. Fig. 7 isa vertical central section of the coupling and protecting-shield. Fig.Sis aview of the coupling removed from its connection to thesignal-staff.

It is designed to construct the parts of the apparatus of metal, usingfor the supports and staffs proper-sized pipe-iron.

A designates the base of the signal-frame, composed of upper and lowermetal plates 1 2, connected by corner bars 3, substantially as shown.The base-frame is set in the ground, and either has the ground firmlytamped about it or it may be set in masonry-work. Arranged in the baseare two vertical supports 4 5, fixed in position and extending up tosuch a height as may bey desired. In the upper end of these supports isjournaled a shaft 6, having a hole 7 arranged transversely to its axisthrough the middle to take and hold the tilting signal-stad, ashereinafter specified. The supports 4 5 are suitably Serial No. 316,515.(No model.)

braced by means of rods 8, having their upper ends secured to across-piece 9, arranged on the supports, and their lower ends carried tothe corner bars 3 `and properly secured thereto. On the upper plate l,between the supports 4 and 5, is secured a bridgetree 10, having astep-bearing in the middle to take the toe of the lower section 11 ofthe staff. This 'section of the staff is projected through a bearing ina cross-piece 12, iixed on the supports, substantially as shown. Theprojecting part of this section of the stad is provided withoppositely-arranged studs 13 14 to engage similarly-arranged slots 22 inthe coupling on the upper section of the staff. At the lower end of thissection is a lever 15, to one end of which is fastened the cable or rodwhich runs to the lookout-house, and is operated by a lever, as usual.The other end of the lever 15 is connected to an elbow-lever 16,fulcrumed on a support 17 on one of the Vertical Vsupports and carryingon its free arm aweight 18, made adjustable thereon. This combination oflevers is arranged so as to always throw the signal in a determinedposition and keep it there until moved by the party in charge.

B designates the upper section of the signal-staff, projected throughthe shaft 6 and carrying the coupling on its lower end and the lamp andsemaphore on its upper end. The lower end of this section B is lixed ina sleeve 19, cored out at its lower portion to readily admit thecoupling.

21 designates the coupling-sleeve, cored out lto slide on the staff andformed with side slots 22, extending part way through it to engage lugs23 on the end of the stalf. On the coupling are formedA handles 24, bywhich the Acoupling may be turned to align with the lugs on the lowersection of the staff if by any means the section should be turned out ofalignment; or should the parts stick together they may be loosened bylmeans of these handles. On the coupling and on the lower section of thestaff, respectively, are staples 25 26, to which a lock may be attachedto hold the parts together and from being separated by unauthorizedpersons. The coupling-sleeve slides on the staff and is supportedthereon by the studs 23 lodging in the ends of the slots or grooves 22.By means of the IOO handles the coupling may be lifted from engagementwith the lower section of the staff, and by the same means it may bedirected and adjusted into engagement when the coupling is to beeffected. On the lower part of the upper section of the staff is anadjustable weight 27 to balance the lamp and semaphore and prevent thetoo rapid descent of the lamp when the stall` is tilted, also to renderthe return easy and certain. On the upper end of the stati is xed asemaphore 28, above which is a seat-nutand a holdingaiut, between whichthe foot of the lamp-frame support is held, substantially as shown. Thesupport for the lantern-frame consists of a metal frame havingafootpiece 30, from which are projected two upright standards Sl 32,bent forward at their upper ends, as seen at 33, so that the lanternwill stand in proper position. At the upper end of the standards is ashaft 34:, on which the lantern-'frame is swung.

The lantern-frame consist-s ot' a metal frame 35, extending' above andbelow the bearingpoint and formed with bearings 36 37 in its lower end,one of which bearings, as 37, is made of larger diameter than the otherto take the larger journal of the lamp. One of the arms of thelantern-frame is extended, as`

at 38, and has arranged thereon a counterweight 39, which keeps thelantern-frame always in a vertical position. The lantern is providedwith journals of different diameters formed to iit, respectively, thelarger and smaller bearings in the frame, and this construction makes itimpossible for the keeper to set the lamp in any other position in theframe than the right one, since it will only go in its bearings in thatcertain determined position. Across the upper arms of the lanternframeis a shaft 40, on which is hungan apron il, extending down and arrangedto rest with its loose end on the shaft 3i. rihe object and use of thisapron is to act against the wind from one direction only-that is, comingfrom the direction against the lodged apron .1.1-- so that the force ofthe wind on the apron, coming in the direction of the arrow, will havethe greater force against the apron, which presents a larger area ofresistance than the lamp, and thus keep the lamp in vertical positionand from swinging outward. When the wind comes from an oppositedirection to that indicated, the lantern is not disturbed, since thewind will swing the apron outward, as shown in Fig. 5 in dotted lines,and operate to seat the lantern more firmly in its position in theframe. To the staff above its shaftis pivoted a hand-rod a, whichenables the operator to tilt the stati and return it to its verticalposition.

The operation of my device is as follows: Then the signal is held inposition-as, for instance, broadside to the eye-by the weight at thebase it displays a danger-signal. To place the signals in positionsignifying safety, the lever l5 is moved by the operator, which givesthe signal-staff a quarterturn and places Ithe semaphore in line to theeye, or this code might be reversed, as desired. At night the samemovement turns the lantern to indicate the signals. To take the lampdown the coupling of the stati? is lifted until disengaged. rlhen thehandrod is grasped and the lower end of the upper sect-ion pushedbackward, when the staff swings down until the lamp is readily reachedby the hand and removed and the staff rcturned to its vertical position.

llaving thus described my invention, what I claim, and desire to secureby Letters Patent,
